Question

Find f(4) for the

piece-wise function.
(x-2 if x <3
x-1 if x ≥ 3
f(x) = {
f(4) = [?]

Answer 1

3

Explanation:

The given piece-wise function is:

f(x) = (x - 2) if x < 3,

(x - 1) if x ≥ 3.

To find f(4), we need to evaluate the function at x = 4.

Since 4 is greater than or equal to 3, we use the second part of the function:

f(4) = 4 - 1 = 3.
